i VALVE :FOR WATER SYSTEMS.

Application filed May 27,

To all whom it may concern:

. -Be. it known that COLUMBUS M. LANE, a citizen oi the UnitedStates ofAmerica, residing at Clarendon, in the county of Donley and State otflexas, has invented new. and useful Improvements in Valves tor aterSystems, or" which the following is aspecitication.

T he present invention. has for its pur- Jose to providea valvefor awater system wherein the waten pressure may betaken carev of .undernormal conditions so that, should there be an increased demand on. thesupply, water from areserve source may be. used to supply. thisincreased demand.

r Another purpose is to provide a valve to be used in a water system,the valve .being open. under normal conditions but adapted to be closedautomaticallyby the water t'ur- .nished under increased,pressure toextinguish fires, so that, during such use of the water underuincreasedpressure, .no water will pass through the normal system.

Still. anotherpurpose is the provision Off a-valve. carried by a guiderod and cooperat .ing with a seat-in one end of a-relatively smallpiping and=being heldnormally-cpen through .themedium of. a spring,inconjunction with a cupped memberon a rodat the other end of arelatively small pipe for the purpose ofreceiving the water andovercoi'ning the opposing force ot the spring, so as to .close the valvein case ofincreased pressure.

A- further purpose isto provide in a valve :1. construction iormultiplying the eiiective force of thestream passingthrough the valvebody and also an arrangement. of a rod-or stem with the elimination ofpacking around the stem which would otherwise .create friction andprevent freeniovement of the roch tion of the valve body,-there beinga-valve seat at one endof the valvebody with which the valve headengages, there also being no parts to cause .undue 'triction.

Moreover, the valve 1IlGlL'lClGS= av cupped inemher' whichmay befastened to the valve rod or stem operable in the path otf the water atthe other end, there being clearance around the valve head and noiriction to retard its movements.

other plugs and loosening the valve head proper with respect to itsstem, the whole working parts of the valve proper can be removedwithoutmolesting the valve body.

It is to be understood that the particulars herein given are in no waylimitative and that while still keeping within the scope of theinvention, any desired n'iodilications of detail and desired proportionsmaybe made inthe apparatus according to the circumstances.

The invention comprisesfurtherfeatures and combinations of parts to behereinafter set forth, shown vin the drawings and claimed.

In the drawings:

Figure 1 is a view in elevation of a portion of a water system pipingshowing applied to a valve constructed in accordance with the invention.

Figure 2 is a sectional View through the valve casing more clearlyshowing the construction of the valve and its mounting, with the valveopen.

Figure 3 is a view similar to Figure- 2, with the valve closed.

-iRe'ferring to the drawings, 1, designates a pipingior a substantialflow ofwater con'iprising an inlet pipe '2 to the valve body and anoutlet pipe 2" from the valve body, there being a pipe 3 connecting theinlet and outlet pipes and adapted to extend to any suitable location toprovide for the consumption of the water. A check valve 3 is located inthe connecting pipe 3 to insure the passage of water through the valvebody rather than through the con necting pipe to the location of thewater consumption.

ltltl The improved valve construction includes proper open during thenormal iiow of water through the valve casing in conjunction with meanson the valve rod with which .an increased supplyot' water under greaterpressure impinges, relying upon the kinetic energy of thestreani ofwater to close the valve. In some stems where it is the aim to employthis in'iproved valve,

lit)

provision may be made for reserve source, so that should there be ademand for an increased supply of water, the reserve source may becalled upon to supply this demand. This valve 2 comprises a casingconsisting of TS l6 and 17 which are axially arranged and are connectedto a reduced pipe section 18 and couplings 19 and 20.

, The remote ends of the Ts l6 and 17 are closed by'means of plugs 21and 22 through which the short sections of pipes 23 and 24 are arranged.The remote ends of the pipe sections 23 and 24 are closed by nuts orcaps 25 and 26. The Ts 16 and 17 have laterally positioned flangedopenings 16 and 16 closed by the plugs 17 and 17". These plugs 17 and 17b may be removed to permit an instrument to be inserted for looseningthe valve proper and a member on the stem of the valve. \Vhen either thevalve proper or said member is loosened, the stem and its attendantparts may be removed by first removing one or both of the plugs 21 and22.

The pipe sections 23 and 2a are threaded through the plugs 21 and 22,there being lock nuts 23 and 24 to hold the short pipe sections inposition, adjusted accordingly.

The pipe section 24 may be adjusted to increase the tension of thespring which cooperates with the stem to hold the valve proper open.Obviously, by removing the plugs 17 and 17", an instrument may beinserted for adjusting the position of the valve proper and the memberon the stem, said member, when adjusted, also governing the tension ofthe spring previously mentioned.

Mounted for movement and guided in the short pipe sections 23 and 2st isa valve rod 29, a suitable web or spider 27 with a guide 28 beingprovided for the medial portion of the valve rod. This web or spiderconstitutes an integral part of the reduced pipe section 18. Securedupon the valve rod 29 by means of the set-screw 32 is a valve 32 whichis designed to cooperate with a valve seat 33 disposed adjacent thecoupling 19. The valve seat 33 constitutes one end of the reduced pipesection 18 which is threaded through the couplings 19 and 20. Alsosecured to the valve rod 29 by means of a set-screw 34 is a cuppedmember 34: which, as previously stated, can be loosened or adjusted byremoving the plug 17" and inserting a tool to accomplish loosening themember. A suitable washer 29 is mounted upon the valve rod 29 adjacentthe inner end of the short pipe section 2% and interposed between thewasher 29 (which bears against the inner end of the pipe section 24) andthe cupped member 3 1 is a coil expan- "sion spring 37. As previouslymentioned,

the tension or this spring can be regulated by adjusting the cuppedmember 34 or by adjusting the pipe section 24. The spring cooperateswith the cupped member and holds the valve 32 normally disengaged fromits seat 33, so long as there is a normal flow of Water through the pipesection 18.

The valve has an adjacent gasket and when the pressure of water in thepipe 2 is greater, the kinetic energy of the stream of water behind andimpinging with the cupped member 34 imparts movement to the cuppedmember and the rod and its valve proper, closing the valve and causingthe gasket to cooperate with the seat to insure cutting oil the water.The valve rod 29 has a collar 29 adjustably secured by means of aset-bolt 29 and which collar 29 cooperates with the spider 27 to limitthe valve in its open position.

When an amount of water under normal conditions is passing through thevalve body, kinetic energy of the water, as it leaves the end of thereduced pipe section 18, is insufiicient to acutate the cupped member,the rod and its valve proper. The action of the water against the valveand the cupped member under normal conditions is not great enough tomove them to any marked degree against the force of the spring. Thus,the water may pass through the piping. However, it will be noted thatthe pipe section 18 is reduced with respect to the pipe 2. Therefore,when the pressure of water in the pipe 2 is greater and since theclearance around the valve ,32 and the cupped member 3a is substantiallyequal to the area of the pipe section 18, the kinetic energy of thestream of water, as it leaves the pipe section 18, increases andimpinges on the cupped member, thereby actuating the valves 32 to aclosed position.

WVhen the supply of water is greater, such as is often necessary forobvious reasons, the action of the water on the valve and cupped memberincreases and obviously overcomes the tension of the spring 37, therebycausing the valve 32 to close against its seat. Prior to the greatersupply of water in the pipe 2*, there is a normal pressure of water inthe pipe section 18. The water under abnormal conditions passes rapidlyout through the T 17 and with substantial energy. The water as it leavesthe section 18 operates upon the cupped member 34 with sufficienteflective force in order to overcome the opposing force of the spring,thus actuating the valve head to engage the'valve seat, a water-tightjoint being assured.

This method of operation throws allthe pressure of the excess watersupply from its source and into a hose which may connect to the pipingin any manner (not shown). However, should the valve 32 be allowed toremain open, the water supply and pressure will be divided between thesource of supply and the source of consumption. .)As soon as the kineticenergy of the water, as it leaves the reduced pipe section:-18, reduces,the spring 37 torcesthe valvezopen, restoring it to its'normal position.The valve is controlled entirely by the effective force of the water.
